just started using log4j in one of my home-projects and I was just about to break out the mouse and cut-and-paste (trace (str "entering: " function-name)) into every function in a large module. then the voice of reason caught up and said "there has simply got to be a better way"... I can think of making a macro that wraps a whole block of functions and adds the traces to them or something like that? Any advice from the wise Stack-overflowing-clojurians?

...or something similar. The most likely extra requirement would be to use filter so as not to call trace on things which aren't ifn?s. Update: edited in a solution to that (also handling macros). Update 2: fixed some major bugs. Update 4: added untrace functionality.
